Design Tips: Reducing BOM items

While running yesterday, I noticed how this treadmill manufacturer used standard 7-segment displays with a decimal point to create a colon. The image shows the manufacturer rotating the 7-segment display and using its decimal point to form a colon for a clock. But why go through this effort? To understand that, let's discuss reducing BOM items and designing for manufacturing.…

Design Tips: Over-Current Protection

Over-current protection is a type of circuit protection that stops your designs from releasing the magic smoke (getting damage). In some ways, most over-current protection circuits help with the over-voltage condition too. It's because as the voltage increases, the current draw increases too. What are our options for over-current protection? The simplest form of over-current protection is adding a current…
